INThODUCTION Previous experiments have given evidence that mouse Sarcomas 37 and 180 produce an agent which promotes the growth of spinal ganglia (1) and of sympathetic ganglia (l@) in the chick embryo. This effect was first observed in experi ments in which small pieces of tumor were im planted in the body wall of 3-day embryos, where they grew vigorously. Later, the same effects were obtained...

Adrenal chromaffin cells, sympathetic neurons, and small intensely fluorescent (SIF) cells are each derived from the neural crest, produce catecholamines, and share certain morphological features. These cell types are also partially interconvertible in cell culture (Doupe et al., 1985a,b; Anderson and Axel, 1986). Thus, these cells are said to be members of the sympathoadrenal (SA) lineage and ...

Expression of vasoactive intestinal peptide (VIP), neuronal nitric oxide synthase (nNOS), choline acetyltransferase (ChAT) and calcitonin gene-related peptide (CGRP) in the sympathetic ganglia was investigated by immunohistochemistry in the superior cervical ganglion (SCG), stellate ganglion (SG) and celiac ganglion (CG) from cats of different ages (newborn, 10-day-old, 20-day-old, 30-day-old a...

I~l a research published by Retzius 1 in 1880, which gives the detailed results of an examination of the various ganglia found in connection with many of the cerebral nerves, the jugu'lar and cer-vical ganglia of the vagus, the jugular and petrosal of the glosso-pharyngeal, the geniculate of the seventh and the Gasserian of the fifth, are described as presenting a structure identical with that ...

We have studied the role of hepatocyte growth factor (HGF)/Met signaling in the development of sympathetic neuroblasts and neurons. Anti-HGF antibodies reduced the number of sympathetic neuroblasts that differentiated into neurons, but neither anti-HGF antibodies nor HGF affected neuroblast proliferation. Anti-HGF antibodies also reduced the survival of neuroblasts but not sympathetic neurons. ...

Fibromyalgia is a painful stress-related disorder. A key issue in fibromyalgia research is to investigate how distress could be converted into pain. The sympathetic nervous system is the main element of the stress response system. In animal models, physical trauma, infection, or distressing noise can induce abnormal connections between the sympathetic nervous system and the nociceptive system. ...
